Pisa syndrome. Report of a case

Very few cases of Pisa syndrome have been reported. The syndrome consists of dystonic symptoms, namely, tonic flexion of the trunk to one side and its slight rotation. It appears to be a side effect of prolonged antipsychotic therapy. We report on a case of Pisa syndrome in which withdrawal significantly improved the dystonic symptoms. However, a severe exacerbation of schizophrenic symptoms required the immediate resumption of neuroleptic therapy which was followed by the reappearance of dystonic symptoms. Associated anticholinergic medication led to only a slight improvement.
